My guess is that's cutting it too close.
I use a pair of the smaller, lighter, and less expensive Optima red tops
in my Cummins 5.9 ISB pickup, and two 34M blue top starting batteries
(each 800 CCA, 1000 MCA, same as red top except for the terminal type)
for my boat's Volvo KAD44. A pair weighs only 77 lbs.

The owner's manual for my Cummins 6BT5.9M states that 950 CCA are needed for
starting. The Optima D31M has 900 CCA and 1150 MCA. Is that cutting it too
close? I like the compactness of the Optima, but I don't want to be "on the
edge."
